Water temperature in Florida summers....
 
Good evening everybody! ^-^

I live in Florida (please don't be jealous, jk jk). My tank is in a large room upstairs. It is the only room on the second story and because it is so large, has its own heating and cooling unit. The airconditioning upstairs is only on while people are upstairs. I love to come up here in the evenings and read while watching my fish.

My question is, that when the air is not on, it can easily get up to 90 degrees upstairs, my submersible thermometer in my tank also says this. If I put the air on enough to make it bearable for me, the temperature will go down to 78-80 degrees. I have not timed how long it takes to drop this much, I only left the air on overnight and checked the next day to see that the temp had decreased. Should I be worried about my fish?

I just invested in some live plants also and am thinking that I am supposed to leave the lamp on all the time...does that also contribute to the temp of the water? Do I really need to leave it on?

Thanks!

I'm not aware of plants helping reduce temperature in a tank. As far as 90 degrees in the house, the fish tank is likely higher. That will likely cause problems with your fish. If you have A/C, you probably should run this during the day as well.

Not the plants, just the light being turned on for long amounts of time. I'll definitely have to do that...at least during the summer. In a few months, I will need to invest in a heater for winter.

I heard that you want 2-3 watts per gallon of water. Is this a fair estimation? I have a 46 gallon aquarium, so I would be looking for 92-138 watts.

Yup, the lights will add heat into the tank. For low light plants (crypts, ...) you can get away with 2W/g. For moderate, figure about 3W/g and for high light plants, 3.5W/g +.

Thanks, I'll try not leaving the light on so much. I am working with my parents to find a way to run the a/c (right now I can't afford to pay the difference in the bill if I ran a/c upstairs 24/7.

Are there any symptoms I should be looking for that would show that my fish are having an adverse reaction to the water temperature? It is at 84 degrees right now and everybody "seems" ok. My yellow male guppy is resting on the bottom of the tank by my anacharis and his gills are moving fast...

HG:

1) The temperature variations are not good for your fish.

2) With respect to the guppy:

As the temperature of the water increases the oxygenation decrease.

It is probably having trouble "breathing".

3) You might try adding an air pump and air bar or air disk in order to increase the turbulence of the water's surface.

This turbulence will help to increase the oxygen saturation in the water and may help somewhat to cool the water via evaporation.

Depending on the amount of time you run it, running the A/C 24x7 can actually be cheaper as it's less to keep a house cool than to do major cool down in the evening every day. Another possibility is a dehumidifier. Removing the humidity from the air in your room will help reduce the impact of the heat (one reason I love living in Colorado :P) as water is more apt to temperature change than plain air.

Temperature is too high at 90 F. Cool the room. A 150w-200w heater would be a good choice for your tank.

Thanks Jones, Leif, and herefishy! You guess have all been a great help. I will definitely look into a heater, and keep an eye on the fishes' gills. I plan to research into a dehumidifier and some additional aeration because I read as the temperature rises the oxygen in the water decreases. You guys are great! I really appreciate the support.

Please let us know the results.

One other item which may be of some help although I do not know the capacity of your tank.

In Canada most folks do not have A/C.

When the summers get above 90F they freeze plastic "soda pop" bottles and put them in their tanks during the day.

The size and quantity of bottles depends on the volume of their tanks.
